Hi there-

I'm looking for some sample code for creating a water scene with
ripples.
The thing I do'nt understand is  how to use waves or ripples inside the
pigment or texture statement as no examples are given in the pov 3.1
docs.
Thanks in advance.

Best regards,

    Waves and ripples are generaly used inside a normal statement.

example:

plane{y,0
  texture{
    pigment{rgbf<.8,.85,1,.3>}
      normal{ripples .4 scale 1}
        finish{ambient .3 diffuse .1 reflection .3}}}

I just did this off the top of my head so if it's not exacly right excuse me.
The priciple is correct though.

Ok, that's easy enough, but...
If you just use a rippled normal, you get to see an annoying repetitive pattern
in the surface. Try blending the ripples with some bumps or something. That looks
much better and 'more randomly'.
